Each ofthe diaphragms 15 also has a wide (lange 18 edge, preferably extendingat an angle of about forty-five degrees riveted to the bottom horizontalmember 19 of the diaphragm which has an angle flange 20 fitting the anle lange 18 and riveted thereto. The horizontal member 19 of thediaphragm also has an angle flange 21 fitting and riveted to the angleflange 22 of the additional or supplemental diaphragm member 23 which isriveted to the upright portion of the diaphragm 15. The bottomhorizontal member 19 is preferably of pressed steel and extends fromside to side of the car and constitutes the bottom tie connectioncrosswise of the car. And it is provided with right angle flanges 24 atthe point beneath the center sills instead of with angle flanges 20where itI is riveted to the diaphragm or transom angle flanges 18 and`22,` as before mentioned. 4

Be it known that I, ARGYLE CAMrBnnL, a citizen of the United States,residing 1n Illinois; havejfw'ented a new and useful Improvement in D'nip orDrop-Bottom Cars, of which the following is a specification.

My invention relates to improvements in dump or drop bottom cars...

In the accompanying drawing forming a part of this specification, Figure1 is a side elevation, partly broken away; showing one half of adumpordrop bottom car embodying my invention. 2 is a plany view of same,partly broken away. Fig. 3 is an en-` larged cross section on line 3-3of Fig. 1.

Fig. 4' is an enlarged, detail partial section, similar to Fig. 3. Fi 5is af'detailcross Fig.r3. Fig. 6 is a dtail, vertical section on line6-6 of Fig. 1. Fig. 7 is an enlarged, detail, vertical section on line7-7 ofl Fig. 1. Fig. 8 is a det-ail, vertical section on line 8-8 ofFig. 3, and

Fig. 9 is a detail, horizontal section on line,

Theextensions 26 of the side sills, preferably channels,y with the flanges3 thereof turned inward or facing each other and extending from end toend of the car and connected at intervals by flan ed connectin Imembers4 by rivets 5 an' by the sheets are furnished with horizontal flangesflange saddles or castings 6 to which the 28 at their lower edges togive additional diaphragme are connected. At intermediate points,similar castings 50, with hinge points 8 to whichthe doors 7 are hingedat their inner longitudinal edges, are connected to` the center sills 2.The flanged saddles 6 and door hinging -castings 50 are furnished withhorizontal slots 9 to receive the bottom flange 10 of an I-beam 11'.,the upper flange 12 of which covers the s ace between the the hingeddoors flange 12 of the I-beam' 11 is 28 are secured by rivets `29 to theside of the car. The upright stakes -30 have right angle flanges 31riveted to 25 of the car.

for connecting the body bolster 32 to the side of the car, two uprightstakes 30 arc placed closely together at the body bolster.

Inclined aprons 33 are provided at each side of the car extendingbetween the floor preferably substantially flush or on a 'level and theside sheets, t-he same being provided with the floor 13 of the car body.The door with flanges 34 and` 35, riveted to the sides hinging saddles50 are wider at their base and ends of the car body.- Angle plates 3Gare also riveted to the upright sides of the car at the floor line.

The diaphragms o1` transoms l5 of the car are provided with connectingcastings 37, riveted thereto and to the upright sides of the car, andthe same are provided withcurved slots or cut away portions 38 to givethan at their top so that the hinge pivots of the doors may come muchcloser together than the center sills 2, 2, the saddles 59. havinginclinedy outer faces 14 to permit the doors to properly swin down inopening.

The transoms or iaphragms 15 have flanges 16 connected by the rivets 5with.

40 crank 51 for .45 middle line of the car,

65 the projecting room or space for the swinging door operating shaft 39to move or swing in.. The swinging shaft 39 for operating the doors issupported bypivot arms or links 40, suspended from pivot pins 41 mountedupon suitable brackets 42 which are secured to and supported by thetransoms or diaphragms 15g directly beneath the inclined aprons 33. Eachof the swinging door operating shafts 39 is provided with a winding drum43 and gear 44, the gear and drum being preferably formed in one pieceandthe drum being preferably furnished with a spiral groove 45 for thechain or iexible connection 46 which connects the swinging operatingshaft with Ythe doors. The hinged doors are provided at their outer orfree ends with supporting bars or pieces 47 which project beyond theouter end edges of the doors and are furnished each with a circularlycurved and toothed head or gear 48, adapted to mesh with the gear 44 onthe swinging operating shaft 39 when the door is raised to near itsclosed position so that the gear heads 48 on the doors will cause theoperating shaft 39 to swing out of the way of said gear heads 48 as thedoor is raised, and then cause the operating shaft to lswing under saidgear and thus support the door in its closed position independent of thechains 46, as will be readily understood from Fig. 3 of the drawing,which shows at the right hand ofsaidfigure the door in 'its openposition, and atk 5o,for opening all the doors, each shaft beingprovided with two winding drums 43 and two gears 44 for each of thedoors, and each of the doors having. two projecting supporting bars 47,each with a toothed or gear head 48. Each of the swinging operatingshafts 39 is suspended from pivot pins 41, located above the swingingshaft 39 through the suspended arms or links 40. As each of the swingingoperating shafts 39 has no contact with the connecting castings 37 orwith the walls of the curved slots 38 therein, the swinging operatingshafts which are journaled in suspension arms or links 40 are free toswing out of the way and around supporting bars 47 when the toothedVheads 48 thereof engage the gears 44 on the operating shaft, and thereis thus no liability for the swinging operating shaft to bind or becomewedged against the walls of the slots 38 under action of y,the toothedheads 48 and gears 44 and consequent fail' ure to properly operateeither in opening or closing the doors. The slots 38 in the connectingcastings 37 are simply for the purpose of giving room for the swingingmovemeflt of the operating shaft 39 when the connecting castings 37 aremade of the pre'- ferred shape illustrated in the drawing, 1t being, ofcourse understood that iflthe connecting castings 37 are so shaped as topermit the operating. shaft to swing as required without the necessityof slotting the same, the slots 38 would, of course, be omitted.
